An agricultural researcher wishes to compare the yield of four different varieties of wheat.64 plots of land are available for an experiment.On each plot of land one of the varieties of wheat will be grown.At the end of the experiment the yield for the different varieties will be compared.32 of the plots are at one site (site
A)and the other 32 are at another site (site
B).The soil at site A differs significantly from the soil at site B.If the researcher wishes to design an experiment using randomized block design,how could the wheat varieties be assigned to the different plots?

The correlation coefficient can only be used for one-tailed tests.
